BREASTINGA ATTACHMENT FOR HEELINGVIACHINES.

SPECIFICATION forming part 'of Letters Patent No. 382,615, dated May 8', 1888. Application filed November $26, 1887. Serial No. 256.236. (No model.) A

being had to the accompanying drawings, and

to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a side elevation of a heel-trimming machine with my improved breaster attached. Fig. 2 is an enlarged side elevation of my improved breasting attachment. Fig. 3 is a front elevation of same. Fig. 4 is a plan view with upper part of frame A removed.

rlhe invention relates to improvements in breasting attachments for boot and shoe heeling-machines; and it consists in the construction and novel combination of parts, as hereinafter set forth.

The breasting mechanism is preferably attached to machines known in the market as the McKay and Bigelow lleeling-lvlachinesf7 and to fully descrbemy invention it is necessary to refer by letter to parts heretofore patented to Allen, No. 310,488; Glidden, No. 374,894; McKay et aZ., No. 166,795; Glidden, No. 203,440, and Allen, No. 332,032; and in the drawings it has not been deemed necessary to illustrate fully the operating mechanism of the machines above referred to.

Referring to the drawings, A designates the frame; B, the spindle; C, the chain carrier lever, and D the chain-carrier.

E and Drepresent the sheaves for the chain; C and F, the carrier for the trimming-lever. Gis the ring of the trimming-lever carrier; H, the forni-plate, and l the trimming-lever provided with the notches tz', by means of which and the pins i i the trimming-lever is vibrated on its center.

J is the nail-block upon which the heel rests, as Shown.

The above-described parts are common in the patents cited, and my attachment is set forth as follows:

PATENTV @Frio-E.v

The link m is" bifurcated and embraces f joint, the said link`m2 being connected to Vthe v shorter arm, Z, of the lever L.

K is an anti-friction roller having its lower end pivoted in the outstanding arm of a bracket, 7c', which is bolted at a suitable point on the lever C. The rollerKeXtends into the cam-slot l Z of the lever L, so that when the lever Gis vibrated the roller moving 4in the slot movesthe cam-lever inwardly when inthe middle of the slot and outwardly when at either end, so that the cam-lever makes two complete vibrations to one made by the chain-carrier lever. `The anti-friction roller rests, respectively, at opposite ends of the slot Z when the lever C is at the opposite points of its vibration.

P is a vertically-reciprocating bar, which slides in aguideway in the block p, forming part of the frame of .the machine above the toggle-joint. The lower end of the bar P is pivoted to the end of the lever n of the togglejoint, and the y`upper end of the rod P is attached to the breasting-knife R and guard Q.

O is a Spring, preferably spiral, situated in a vertical recess, o', inthe block o, which is secured to theumain frame below the togglejoint-in a vertical line with the block p. Vis a plate above said spring provided with a central standard, to which the lower end of the lever n is pivoted. The spring has an upper v the shank'of the shoe being operated upon,

and prevents the knife from cutting into the sole, as the cutting-edge of the knife and the upper end of the guard are usually on the same level. The coiled spring acts as a cushion and allows the knife and guard to give slightly downward.

The knife and guard have their respective Shanks secured to the carrying-bar by screws or bolts, and the said shanks are vertically adjustable on said bar, so that the knife can be elevated to compensate for the wear of its edge, and the guard can be raised slightly 'above the knife-edge when operating on soft leather, into which the guard has a tendency to sink.

The breastingknife and guard move through a suitable opening in the plates G, H, and I, and the knife R passes up against the edge of the nail-block, so as to cut the edge of the heellifts in a line with said block.

X is a thin metallic protecting-plate secured over the plates of the heeling-machine below the nailing-block, to prevent the cut pieces of leather from falling into the guideopening for the knife and guard.

When the chain rotates the head of the heeling-machine to trim the convex surfaces of the heel, the breasting-knife and guard, actuated by the cam-lever, links, and toggle- 3o joint, begins to rise and cut the front of the heel, and rises to its full height when the said head has rotated half-way. It then descends, so that the carnlever makes twovibrations to one of the chaincarrier lever, and thus the breasting-knife and guard can never be in the way of the trimming-knife.

Having described my invention, I claim- 1. In breasting attachments for heeling-machines, the combination, with the vertical1y-reciprocating knife,and the guard having its upper end bent over at or near the same level as the edge of the knife, and both knife and guard reciprocating simultaneously, of mechanism, substantially as described,whereby said knife and guard are moved to their highest points when the head of the machine has made onehalf of its rotation, substantially as specied.

2. In breasting attachments for heeling'machines, the combination, with the knife and guard secured to and reciprocating with a vertical bar, the knife and guard being vertically adjustable on said bar,of the togglejoint attached to the lower end of said bar and connected with the main frame of the machine, and mechanism, substantially as described, to actuate said toggle-joint, substantially as specified.

3. In breasting attachments for heeling'machines, the combination, with the knife and guard-bearing bar reciprocating vertically in a guide opening in the main frame,of the toggie-joint attached to the lower end of said bar and connected with the main frame, the doublearmed cam-lever journaled on a bearing secured to the main fraaie and connected by links to the toggle-joint, and means, substantially as described, whereby said lever is vibrated to actuate the toggle-j oint, substantially as specified.

4. In breasting attachments for heeling-machines, the combination,withthe vertically-reciprocating knife and guard-bearing bar, the toggle-j oint attached to said bar and connected with the main frame, of the double-armed camroller connected to the togglejoint bysuitable links, the actuating-chain for the rotation of the head, thechain-carrier, the chain-carrier lever, and the canrroller attached to said lever, substantially as specified.

5. In breasting attachments for heeling-machines, the combination of the reciprocating bar P, the guard Q, attached thereto and vertically adj ustable thereon, the knife R, attached to and vertically adjustable on the same, the toggleg'oint N, the plate V, the coiled spring O, the plate W, and adjustingscrcw S, all constructed and arranged substantially as and for the purposes specified.

In testimony whereof I aix my signature in presence of two witnesses.
